822 Lalage (prov. designation: A916 GJ or 1916 ZD) is a background asteroid from the inner regions of the asteroid belt. It was discovered on 31 March 1916, by astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory in southwest Germany.[1] The likely highly elongated asteroid with an unclear spectral type has a short rotation period of 3.3 hours and measures approximately 9 kilometers (5.6 miles) in diameter. Any reference to the origin of the asteroid's name is unknown.[3]
